BOTTLE-STOPPER.

Specification of Letters Patent.

Patented Sept. 8, 1908 Application filed September 6, 1907. Serial No. 391,719.

To all whom "it may concern:

' Be it known that I, THEODORE B. HAF- STAD, a citizen of the United States, residing at Iron Mountain, in the county of Missoula, State of Montana, have invented certain new and useful Improvements in Bottle-Stoppers and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention has reference to stopper fasteners for bottles or analogous vessels, and it aims to rovide an extremely simple device of that c ass which may be secured to the bottle during its manufacture without materially increasing the cost thereof, and which, when in place upon the bottle neck and connected with the stopper, will effectually prevent the withdrawal of the latter.

To this end the invention comprises a wire fastener in the shape of an elongated loop, which is completely embedded intermediate its ends in the bottle neck, one strand being disposed upon each side of the bore thereof, the proj ecting loop ends being bent upwardly and then folded one upon another a ainst the upper face of the stopper, which atter carries a rivet Whose up or end is permanently connected with said 100 ends.

The invention will be readi y understood from a consideration of the following detailed description, and itspreferred embodiment is illustrated in the accompanying drawings in which like parts are designated by corresponding reference numerals in the several views.

Of the said drawings, Figure 1 is an elevation of the neck of a bottle in which the stopper is held in place by the improved fastener,

ig. 2 is an enlarged top plan view of Fig. 1, showing in dotted lines the position of the wire embedded in the bottle neck, Fig. 3 is an enlarged horizontal section through the bottle neck, illustrating the formation of the grooves therein, Fig. 4 is a vertical section through Fig. 2, Fig. 5 is a fragmental detail view of the bottle neck showing the terminals of the grooves. Fig. 6 is a top plan view showing the position of the loop ends prior to bending the same against the stopper.

Referring more particularly to the drawings, 7 designates a bottle or analogous vessel, whose neck 8 is provided adjacent its upper end with a pair of arcuate oppositely-disposed grooves 9 formed internally therein during the manufacture of the vessel, the opposite ends of the grooves communicating with the outer face of the bottle neck, as shown. The grooves are approximately concentric with each other and with the neck opening, and are disposed upon opposite sides of the latter.

Embedded withinthe grooves is a fastening device 10, composed of a single stri of extremely thin wire, whose ends are we ded together to form a closed elongated loo the central portion of the members of sai loop being disposed within the arcuate grooves, as above stated. The length of the loop is such that its opposite ends extend through the terminals 11 of the grooves and project therebeyond, as shown in Fig. 6. Owing to the fact. that the grooves are approximately semi-circular, the central portion of the loop will have a much greater width than the end portions. The fastening device is preferably secured to the bottle neck during the blowing of the bottle.

Fitted within the opening in the bottle neck is a stopper 12 of any preferred description, across whose upper face the projecting loop ends 13 are bent, the length of said ends being such that they overlap each other slightly. The stopper is, in turn, provided with a bolt or rivet 14 permanently fastened thereto, the head of which is engaged with the overlap ing portions of the loop ends 13, which atter are bent over the bolt head. The strain upon the loop ends requisite in engaging them with the bolt head will hold them in place.

From the foregoing, it will be apparent that when the loop ends are engaged with the bolt head any attempt to directly withdraw the stopper will result in breaking one or both of said ends, by reason of the extreme thinness of the wire of which they are formed, the outward movement of the stopper incidental to its withdrawal having the effect of straining the ends to the point where they are bound to snap. In like manner, even if the loop ends could be disengaged from the bolt head, the bending of said ends backwardly to permit the stopper to be withdrawn, and their subsequent bending forward when the stopper is reinserted would have a similar effect for the same reason as will be apparent.

While the invention has been shown and described inconiiection'with a'bottle, itis' to be understood that it is equally capable of use in connection with any analogousvesselr What is claimed, is, 1. A bottle or analogous vessel having its neck provided at the upper end thereof with a pa'i-r'of oppositely disp'osed arcuate grooves" formed internally therein;=each groove having its ends communicating with the outer surface of the bottleneck; a'stopper fitted in the bottle neck; a fastener inthe form of' a closed'loop havingth e central portion of 'its members embedded in'said'grooves, the opposite ends-of said loopf rojecting beyondsaid grooves exteriorly of t e bottle neck and being overlapped against the upper face of semi-circulargro oves formed internally-therein and'arranged at opposite sides of the neck opening,- each g roove ha ving its ends communicating with the outer surface of the bottleneck'; a stopper fitted in the bottle neck; a single strip of wire having its ends connected to forma closed loop, the centralportion of ,the'members ofsaid loop being embedded in said grooves and the opposite ends of the loops projecting therebeyond exteriorly ofthe bottle neck, said projecting portions being bent" upwardly and overlapped directly againstthe upper face of the stopper; and a member permanently fastened in the stopper andfengaged with the overlapping portions of' said loop ends, to prevent displacement of' the latter from such position.

In testimony whereof; I affix my signature} in presence of two witnesses.-

THEODORE B. HAFSTAD.
